Of those, 5 is not composite.
The numbers 20, 21, 22, 24, 25, 26, 27, 28, 30, 32, 33, 34, 35, 36, 38, 39 and 40 are composite (including the boundaries).
The odd composite numbers less than 50 are 9, 15, 21, 25, 27, 33, 35, 39, 45, and 49. These numbers are odd and have divisors other than 1 and themselves, making them composite.

The odd composite numbers are 9, 15, 21, 25, 27, 33, 35, 39, 45, 49, 51, 55, 57, 63, 65, 69, 75, 81, 85, 87, 91, 93, 95, and 99.Composite numbers are those numbers that can be expressed as the product of any two integers greater than 1. So they are all numbers that are not prime numbers.9, 15, 21, 25, 27, 33, 35, 39, 45, 49,51, 55, 57, 63, 65, 69, 75, 77, 81, 85,87, 91, 93, 95, 99.
It is 37 which is a prime number because it has only two factors
